Weaknesses: everything. needs constant adjustment I use locktite and tourqe the hell out of it it moves around every few rides

Bottom Line:

DONT BUY IT......... THE E.THIRTEEN IS HASSLE FREE. THE PROBLEM OCCURS WHEN YOU TAKE BIG DROPS AND THE CHAIN PUSHES UP ON THE BOX AND ITS PLASTIC SO EAVEN WITH IT REAL REAL REAL TIGHT IT EVENTUALY MOVES AND AFTER THE THIRD TIME THE CHAIN WILL FALL OFF AND THEN BREAK OUT THE TOOLS CAUSE THATS THE ONLY WAY TO GET THE CHAIN BACK IN THE BOX.

I have been using it for the last 3 months with no problem. My bike came with a 38 tooth chain ring and it worked with that. I ended up switching to a 32 tooth to be able to do some climbing and it works fine with that too. If it didnt come on the bike i would probably go with e13, especially because i cant run a bashguard with it. Its not terrible, but not amazing.

I've never given a product 1 out of 5 before but this is just ridiculous... The crap piece of plastic up on the top always rubbed somewhere and bent so i took it off. The wheel at the bottom has got far too much play => it was not straight => the whole drivetrain had noticable friction AND once i took the whole chainguide off, the chain has basically always stayed in place. with it on do a bunny hop => chain is off ===> this product is no good. In fact: its a disgrace.

Strengths: the lower roller never had any problems keeps the chain tight, it indure abuse and its simple

Weaknesses: the chaine guide itself, its just plain crap it keeps getting loose, it dosent hold the chain very well unless u spend a while adjusting it but as soon as as u ride in rough terrain its gets loose and the chaine falls off so if ur sprinting its gonna hurt and dont even think about putting a bashgard because you have to take off the side of thye chaine guide and if u do that u might as well take it off.

Bottom Line:

if u are just looking for the lower part then go and buy it it dosent get much better than that but if u need the whole thing or just the chainbox then go look somewhere else like mrp or e-13

Similar Products Used: e-13 LG1 and STS the best chaine guides i have ever seen!

Bike Setup: o6 big hit stock except for a few things here and there

Strengths: Works very very well, sets up perfectly if you just follow the directions. Light in weight, very well built, adjustable for any chainline/chainring size between like 32 / 44t. Great flexibility, fits pretty much any frame configuration.Team version with the sealed bearing jockey wheel has the lowest resistance of any chain device I have used so far, you really don't know it's there when you're pedaling, however the chain NEVER comes off.Cheap - about half the price of MRP or E13, and works at least as well, if not better.. won't go back to either of those again.

Weaknesses: None, does exactly what it is supposed to.

Bottom Line:

It's a great product. Be sure you get the team version which uses a high quality sealed bearing on the jockey wheel. I honestly don't know how some of these people are saying it's hard to set up. If you follow the directions exactly (not rocket science BTW), it sets up correctly the first time. Just use Loc-Tite on the bolts, and it's going to run trouble free.Great set and forget chain guide. I haven't had to touch it since I installed. takes maybe 20 mins to set up properly if you take your time and double check everything. No complaints at all.

Weaknesses: If I set it wrong the chain eats the plastic upper part. you have to "mod" it to fit a rockringmakes horrific noise when the lower wheel is not lubricated, or the chainline is not about dead center.

Bottom Line:

ok, this is my introduction to the world of chain guides. The chain has been on so far. took some time to set it right. no huge problems yet, so a new mrp/e13/blackspire is not on the shopping list.

Weaknesses: lots of fiddling to get it set up,smallest chain ring you can run is 34t, anything smaller you need to start modding it.makes pedalling bit more of an effort.

Bottom Line:

if you can afford to pay a few hours layber to the local bike shop to set it up go for it,if not then you need alot of patience or hopefully you fluke it, cant run any smaller chain ring than 34t with it on, noisy unless you get the sealed team version, honestly i spent hours getting it lined up,used it for two days and took it off again,rather have a tight chain and custom a front derailluer with a bash plate,does a better job,more quiet and can run any size chain ring i want. having said all that this is still better than some chain guides!!!!!!1

Strengths: amazing i love this thing, when set up by the right bike shop they will put time into putting it on correctly and it works. it is so quiet. the noise is the exact same from when it wasnt on and it keeps th chain on.

Weaknesses: none so far!

Bottom Line:

amazing, worrth the 100 dollars just i would reconmend a bike shop set it up cus it can be tricky.
